Why Builders Can Offer Lower Rates Than Banks

The Ad You've Probably Seen

"5.5% financing available on select homes."

You see that on a billboard. The market rate is 6.5%. You wonder how a builder can offer a full point below the market when every broker, bank, and lender you've talked to is quoting something higher.

The answer isn't that the builder has access to some secret discount nobody else can get. It's that the builder has more capital in this specific transaction than a traditional seller does — and the money for the rate buydown is coming out of the same budget that pays for the house.

Phillippe Lord, the CEO of Meritage Homes, walked through this exact mechanic on a recent interview with Steve Eisman on The Real Eisman Playbook (Weekly Wrap episode, March 27, 2026). Meritage runs a captive mortgage company, so they see both sides of the trade — the home sale and the loan. Here's what he described, translated out of builder-speak.

How a Rate Buydown Works

A mortgage rate isn't a single number. It's a spectrum. At any given moment, a lender will price the same loan several different ways:

Higher rate, cash back to you (credit at closing)
Market rate, no points, no credits (par pricing)
Lower rate, you pay upfront (points)

A "point" is one percent of the loan amount paid upfront in exchange for a lower rate. On a $500,000 loan, one point is $5,000. That money goes to the lender to permanently lower the rate on the loan — typically by somewhere between 0.125% and 0.375%, depending on the market.

To buy a rate down by a full percentage point — from 6.5% to 5.5% — you might need to pay three or four points. On a $500,000 loan, that's $15,000 to $20,000 paid at closing.

That's the lever. Whoever pays the points decides who gets the lower rate.

What the Builder Does

When you see an advertised rate from a builder, the builder is paying the points on your behalf. That money is going to the mortgage company — usually a captive mortgage lender that the builder owns or has a joint venture with — to lower the interest rate on your loan.

The buyer genuinely gets a lower rate. The monthly payment is real. Over thirty years, a one-point reduction adds up to meaningful interest savings.

It's not a gimmick. The rate is what it says it is.

But somebody paid for it. The question is who, and where that money came from.

Can a Traditional Seller Do the Same Thing?

Yes — up to a point. A homeowner selling an existing house can contribute to the buyer's rate through seller concessions. Conventional and FHA loans cap seller concessions at a percentage of the purchase price — typically 3% on a primary residence with less than 10% down, sometimes higher with a larger down payment. On a $500,000 home, a 3% cap is $15,000. That covers closing costs and can fund a modest rate buydown — maybe a quarter-point permanent reduction, or a 2-1 temporary buydown over two years.

So traditional sellers do have this lever. It's just a bounded one.

Builders have more capital to work with. They own the full cost structure of the home — the land, the construction, the margin, the captive mortgage relationship. They can route significantly more dollars toward the rate than the concession caps allow a traditional seller to spend. That's why a builder-advertised rate can be a full point or more below market when seller contributions on a resale would cap out at a partial point. It's not that sellers can't do it. It's that builders have more ammunition.

Where the Money Comes From

When you're negotiating the price of a home, the builder has a budget for the transaction. That budget includes the land cost, the construction cost, the regulatory and permit costs, marketing, overhead, and margin. Every dollar the builder spends buying down your rate is a dollar they could have used to lower the sticker price of the house — if that's a lever they're willing to pull.

If the builder's budget allows for a $20,000 rate buydown on a $500,000 home, that's functionally equivalent to a $20,000 price reduction financed at 30 years, in the cases where the builder would actually offer the price reduction instead. That's an important qualifier. In many cases the trade-off isn't really on the menu. More on that below.

The Math on Buydown vs. Price Reduction (If You Have the Choice)

Here's an illustration to show how the trade-off works when a builder is actually willing to price both ways. Numbers rounded for simplicity.

Say the builder offers you two options on the same home, priced around $500,000:

Option A: Pay full price with a bought-down rate (builder pays the points to get you a lower rate)

Option B: Pay a reduced price at the market rate (builder gives you the equivalent amount as a price cut instead)

Option A gives you a lower monthly payment because your interest rate is lower. But you are financing the full sticker price — so your loan balance, your property tax basis, and your homeowner's insurance are all based on the higher number.

Option B gives you a lower purchase price at the market rate. Your monthly payment is higher than Option A. But you started with a smaller loan.

At first glance, Option A looks better. Lower monthly payment, same house.

But consider what happens when you either refinance or sell. Under Option B, your starting loan balance is smaller, so you build equity faster and you owe less at any point in time. If you refinance in three or five years, you refinance a smaller number. If you sell, you walk away with more equity.

The general rule: the rate buydown wins if you plan to keep the mortgage and the home long-term. The price reduction wins if you're likely to refinance or sell in the first several years. Your own breakeven point depends on the specific numbers, the rate environment, and how long you plan to hold the loan. Run the math on your actual scenario before deciding.

Neither is a trick. Both are real. But they are not the same deal.

The Honest Caveat: You May Not Actually Have a Choice

The math above assumes the builder will price the deal both ways — full price with a bought-down rate, or a reduced price at the market rate. In practice, many buyers find that the second option isn't really on the menu. Builders set pricing and incentives, and what they're willing to negotiate is usually narrower than "rate or price, your pick." The advertised buydown is often the only incentive being offered, and asking for a price cut instead may get a polite no.

That doesn't make the buydown a bad deal. It just means the framing of a free choice between two equivalent paths isn't how most new-construction transactions actually work. Knowing that going in helps you calibrate the conversation.

What to Ask Before You Sign

If you're considering a new home with a builder-advertised rate, here are the questions worth asking, in order.

Can I shop this? Yes. A broker can quote the same loan scenario from multiple lenders and compare it against the builder's in-house offer. Sometimes the builder's offer is genuinely better. Sometimes it isn't. You don't know until you compare — and asking to compare tells the builder you're a serious buyer, not a walkover.
What realtor should I use? This question matters more with new construction than with resale. Builders have their own on-site sales staff, and their job is to represent the builder — not you. A buyer's agent (a realtor you hire) represents you, negotiates on your behalf, and reviews contract terms the builder's sales staff won't flag. You can bring your own realtor into a new-build transaction, and in most cases the builder pays the commission. If you don't have one, get one before you sign. This is one of the most underrated protections a buyer has in a new-construction deal.
Is the buydown permanent or temporary — and can I make it permanent? Most builder-advertised buydowns are temporary 2-1 buydowns: the rate is two points lower in year one, one point lower in year two, and back to the full note rate for the remaining 28 years. A permanent buydown keeps the rate lower for the full life of the loan. They're very different products. Ask directly: "Is this a permanent or temporary buydown? If it's temporary, can you price a permanent one instead, and what would that cost on this transaction?" You may not get the permanent option, but asking puts it on the table.
What does "effective interest rate" actually mean here? "Effective interest rate" can mean different things in different hands. Ask the builder to define it specifically. Are they using APR (which blends the note rate with closing costs)? A weighted rate across the teaser and full-note years of a temporary buydown? Or some marketing math that treats a hypothetical price reduction as a discount the buyer didn't actually receive? The version that matters is the one you'll pay on the money you're actually borrowing. If a builder calculates an "effective rate" by assuming a lower price you were never offered, that's marketing math, not a number that shows up on your loan.
What's the price if I bring my own financing? This is a negotiation question, not a first question — but once the rest of the deal is on the table, it's the right one to ask. If the builder won't lower the price when you forgo their financing, the buydown is effectively a price lock and you have your answer. If they will lower the price, you now have a concrete number to compare against the bought-down-rate offer. This is how you find out whether the rate-vs-price choice from earlier in this article is really on the table for you.

The Takeaway

Builder rate buydowns aren't a trick. The rates are real and the savings are real. Traditional sellers can contribute too, within seller-concession caps — builders just have more room to work with because they own the whole transaction.

If you're looking at new construction and the builder is offering a rate significantly below the market, run the numbers two ways: once with the builder's financing, and once with an outside quote. The rate tool lets you model both scenarios side by side — rate, APR, points, credits, and breakeven — so you can see what each option actually costs over time.
